A RATE is a comparison between two different measurements.
It is a special type of ratio where the units are not the same, such as cost (price per item), speed (distance per time) or rotations per minute (RPM), which is used to measure spin in ice skating and rotation rate pedalling on a bike.

Hellloooo Little MathZ Luvvies,
Mathspig has gone quite Zombie Mad and I have decided to put the entire Year 8/9 curriculum into Zombie MathZ.
There will be 13 posts all involving Zombie MathZ …… and to kick off all this Zombie MathZ going on in your head … in your head … in your h-h-head ……..

Prime Target: Prime Numbers Rule the World, sort of
February 5, 2025
In the Apple TV show, PRIME TARGET, a young mathematician’s life is in danger because of his work involving PRIME NUMBERS:
2,3,5,7,11,13,17,19,23,29 ……..
In the TV series all global security codes are based on randomly selected Prime Nos. What if the selection is not RANDOM? If this code breaking information gets into the wrong hands the world is in danger.
Or NOT
If you saw a number like the following you may think Prime Numbers Rule the World. almost:
9 3 0 0 6 0 7 1 7 9 1 2 5
One code that uses lots of PRIME (and other) NUMBERS is the BARCODE. And this is how they work.
The cash register pings if the BARCODE CHECK DIGIT Algorithm matches the CHECK DIGIT, which is the last digit in the barcode. This is how the cash register computer checks that the data in the barcode has been transferred correctly. All data transfers have some sort of data check algorithm.
The PING is KING!!!!!!!!
Mathspigs, you can check your maths skills by picking up the nearest product with a 13-digit barcode and calculating the CHECK DIGIT. The answer is at the end of the barcode.
How a BARCODE works:
You can find an alternative explanation here.
If your calculations won’t work use the online CHECK DIGIT CALCULATOR (EAN 13). If it is right check your calculations again!!!!!!
Fun Math: Use Google Maps to find streets with Mathsy Names
December 20, 2024
Reading Undiluted Hocus-Pocus, the autobiography of Martin Gardener, mathematician and magician (He wrote the puzzle column for scientific America for years), Mathspig was bemused to read that statistician William Feller lived on Random Road in Princeton.
Mathspig totally confused Google Maps by searching for so many Maths streets, roads, drives, lanes and crescents. Mr Google began to think Mathspig was stuck on Infinity Street or lost at Cartesian Place.
What place boasts the most mathematical street names in the world (so far):
1. Paris
There are nearly 100 Parisian streets, squares, boulevards etc. named after mathematicians and not necessarily French mathematicians.
Street names include:
Rue Laplace
Rue Bernoulli
Rue Newton
There is, surprisingly, no street named after Fourier in Paris. But the street on which he was born in Auxerre has been renamed after this great mathematician.
.
2. Salisbury, South Australia
Surprisingly, the most ‘mathsy’ place Mathspig has discovered so far is an outer suburb of Adelaide, south Australia. Maths street names include:
Equation Rd
Parallell Ave
Chord Rd
Log Rd
Tangent Ave
Quadrant Ave
Meridian Rd
Degree Rd
Decimal Rd
Latitude Rd
Co-ordinate RD
Fibonacci in Budafest
Not by name, by design.
3. New York, NY, USA
You can’t get lost in New York. It is a grid city.
Eg. 812 East 23rd St means No. 12, block 8 East of Broadway.
There is a Sine Rd in Auburn New York,
but it’s not this one. Pity!
Here is a fun Maths exercise to get Middle School students thinking about maths.
…………………………………………………………………………………
Ans. 1. Massey, NZ. 2. TRIANGLE. 3. State Ave 4. 0.7 miles, 1.1 km. 5. It has 3 right angles 6. 0.4 miles, 0.6 km. 7. No. The triangle is not a right angle triangle. 8. David W Carter Hight School) 9. Only 2 ARITHMETIC CR, Landon, SC and ARITHMETIC Dr, Salem, MA. 10. O.4 miles, 0.6 km.
